The x and all factors for which is_finite is not True should be retained in
a product so that a proper determination of the value can be made once
those quantities are substituted/evaluated.
For example, 0*inf (as defined below) should probably not be zero:
r
-sqrt(2) + 1
inf
sqrt(3)/(-sqrt(2) + sqrt(2)*(-sqrt(2) + 2)/2 + 1)
So although 0*pi == 0, 0*pi*x*inf should be 0*x*inf.
